As far as I know, antibodies are the body's own defence against infection and antigen's stimulate the body to produce antibodies.

I dare say Chris will show me to be totally wrong.  []

Hi Paul.fr,

you may refresh your knowledge
about viral infections and go to
page 5 for a definition of Ag and Ab.
Take care

Antigens are molecules that the immune system uses in responding to a target. In other words, antigens are like the molecular fingerprint of a cell, bacterium, virus or fungus. Antigens are usually proteins or pieces of protein.

Antibodies, on the other hand, are Y-shaped proteins made by B lymphocytes (plasma cells) that can recognise antigens. The tips of the Y are known as hypervariable regions which are programmed to bind antigen by shuffling genes.

Yes D.B.,

you had to click my previous link (digit: 5)
to open a splendid pdf with a proper 'box'
about antigen and Ab definition.
Plus an update on viral diseases...

Oops... I hadn't realised it was a link. I thought it was just a weird reply!  [:I]

I apologize for my temporary 'hidden-link' crisis.
Yes, it was a bit tricky!
